UFO Sighting in New Philadelphia, Ohio on October 17th 2012 – watched ufo flying south along interstate 77 after work going home

I just had gotten off work in new philadelphia around 5:30pm and was driving home to newcomerstown on interstate 77 south in October of 2012. I was a few miles south of new philadelphia when I noticed a cigar shaped craft flying parallel to the interstate. It was between 30��and 40�� of elevation and stayed between my 10 o'clock and 11 o'clock during my entire observation. It was about 2 inches long and about 1/2 inch high from my advantage point. It had no wings that I could see, I rolled down my window to see if I could hear an engine, I couldn't, and there was no jet trail left behind in its flight path so I knew it wasn't an airplane or jet almost immediately. It stayed in roughly the same position from me for the next ten to fifteen miles until the newcomerstown exit. I couldn't tell how high the object was until it flew over some clouds that were either altocumulus or cirrocumulus in rows. It was at that point I knew it had to be very large. I once lost sight of it due to the terrain, but picked it up right where it should have been if it hadn't changed its course. I felt exhilarated the entire time because I seeing something I couldn't explain what it was.
